Earlier today, we reported that 6 Bing apps in Windows Phone Store was updated with Microsoft Account sync support. Microsoft posted the above quick video demo to show how this sync feature will work in Bing apps. This new feature will enable you to keep your Bing apps across Windows devices like tablets, PCs, and mobile phones in sync. For example, if you add a weather location on mobile in Bing Weather app, it will automatically show up in Bing Weather app installed in all your other devices. In the Finance app for example, when you setup your stock watch list on Windows 8, it will show up the same way on the Windows Phone. Same applies for Bing Sports, Bing News and more.
